How to detect which hardware has non-free firmware available

[CarterCox]

Hi! I am using Debian 9.3 and I want to install al the non-free firmware available for my computer hardware. Is there any way to find which ones do I need? I have tried running

Code: Select all

apt search firmware

and manually located and installed "intel-microcode", but I believe there may be others (such as network adapters, sound cards, etc.) that may need firmware, so is how can I do this?

Thank you.

A lot of the time you will be able to find that in dmesg which is the log that is created when the system is enumerating the hardware during boot. Probably something like a message that firmware isn't found.

Of course, some piece of hardware that doesn't work is often a good indication too.

[edit] I guess I should also mention the Debian Wiki in case you aren't familiar with it..

There are some threads on this forum about the microcode fiasco, you might want to review them too just for fun.
